The short version

Each has a real cost: Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keycloak

Requires self-hosted deployment and operational expertise to install, configure and maintain
No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
Clustering and high-availability configurations require additional operational knowledge
Community support only; commercial support requires third-party vendors or distributions

Trivy

Reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
No built-in triage or exception workflow, so suppressing accepted risk is managed in config files
Findings are point-in-time from CI, with no continuous runtime monitoring unless you add the commercial platform
